Siemens Gas Turbine
SGT-2000E Series
Reliable, robust, flexible
Answers for energy.
The SGT-2000E series –
designed for reliable, robust,
and flexible power generation
Ongoing fierce competition
fueled by deregulation is
dictating increasing flexibility
and lower power generation
costs. One approach to
­cost-cutting is economical
plant operation based on
low investment costs
combined with high
­flexibility and ­reliability.
The SGT5-2000E Siemens Gas Turbine
(SGT™) – our well-established
workhorse – is created to meet these
requirements. With its proven design,
materials, and thermodynamic processes,
the SGT5-2000E helps keep you strongly
positioned in a highly competitive market.
The SGT6-2000E is the corresponding
60 Hz model.
This machine is characterized by a
long-established design concept:
■■ Two rotor bearings
■■ Cold-end generator drive
■■ Built-up rotor with Hirth serrations
and central tie bolt
The combination of this proven design
and innovative features means:
■■ Low investment costs per installed
kilowatt
■■ Fuel flexibility
■■ Operational flexibility
■■ Low maintenance expenditure
■■ Long service life
■■ Fast payback on invested capital
Based on the standard design concepts
of our modular reference power plants
for multi-shaft application, we have
identified several solution packages
for the SGT5-2000E. These packages ‒
from components to the SGT-PAC to full
turnkey solutions ‒ support all your
requirements. The intelligent structuring
of our power plants, offering a wide range
of modules and options, provides you
with many benefits.
This gas turbine concept draws on decades
of experience with heavy-duty gas turbines
at Siemens. This accumulated expertise
is the solid technical foundation on which
this proven technology is based, and
ensures reliable, efficient, and flexible
operation.

By July 2011, more than 400 SGT5-2000E
and SGT6-2000E Siemens Gas Turbines
were in operation worldwide.
The 168-MW 50 Hz model, the
SGT5-2000E, is a heavy-duty gas
turbine designed for reliable, efficient,
and flexible operation. Over 6.4 million
operating hours of experience with
300 SGT5-2000E gas t­ urbines have
been accumulated, demonstrating their
outstanding reliability under a wide
range of operating conditions.
The SGT5-2000E proves that it is possible
to reconcile ambitious economic and
environmental targets. Despite its high
flexibility in terms of ­operation and fuels,
the NOx and CO2 emissions of
a ­SGT5-2000E are minimized.

Proven design features –
derived from decades of experience
Optimized flow, robust
and versatile combustion and
cooling systems add up to
a gas turbine efficiency of
nearly 35 percent.
■■
The machine features a single-shaft,
single-casing design and two laterally
flanged, large-volume, silo-type
combustion chambers, a multi-stage
compressor, and a four-stage turbine.
An air-cooled generator is driven on
the cold (compressor) end.

■■
1 Compressor blades
■■
■■
Variable-pitch inlet guide vanes allow operation down to half
load while maintaining a constant e
­ xhaust temperature.
All stationary and moving blades in the compressor and
turbine can be replaced individually without removing
the rotor from the lower casing.
3 Rotor
■■
The light, highly rigid rotor of disk design allows rapid startups.
■■
Internal air-circulation paths in the rotor minimize thermal
stresses.
■■
Hirth facial serrations at the outer perimeter of the disks ensure
self-centering of all the rotor components under steady- and
non-steady-state operating conditions.
2 Turbine blades
■■
4
Convective air-cooling of the first three stationary and first
two moving turbine blade rows protects the blade material
against high inlet temperatures. The first three stages of the
turbine are protected with a special coating.
■■
To allow ash-forming fuel firing, no film cooling is used.
■■
The free-standing moving blades of the compressor and
turbine are tuned to permit continuous full-load operation
over a wide off-frequency range.
Compressor stages:
SGT5-2000E: 16
SGT6-2000E: 17
A modified version with 17 compressor
stages is available for non- or partially
air-integrated syngas / IGCC applications.
Burners per combustion chamber:
SGT5-2000E: eight
SGT6-2000E: six
A standard static-excitation and
variable-frequency converter system
ensures smooth acceleration of the
gas turbine to full speed within four
minutes.
Easy access via manholes into the two
combustion chambers permits ­direct
inspection of the hot gas-path components, from the burners to the turbine
blading.
4 Combustion
■■
Two silo-type chambers with ceramic heat shields.
■■
Hybrid burners with dry low NOx technology.
■■
Gaseous and liquid standard fuel firing.
■■
Special gaseous fuel firing, for example, low-Btu gas
and syngas from IGCC.
■■
Special liquid fuel firing, for example, kerosene, naphtha,
and ash-forming fuels (crude oil, heavy fuels).
Operational flexibility and servicefriendliness – for challenging operating
conditions
Large c­ombustion chambers
ensure low emissions, fuel
flexibility, and ease
in maintenance.
3
The SGT-2000E series can be fired with
a wide variety of fuels, from low- to highcalorific gaseous and/or liquid fuels,
including treated heavy oils.
Off-board combustion eliminates
any ­direct flame radiation on the
turbine blading, and the long dilution
path allows for long service intervals
and high availability of the hot gas
casings.
The basic robust design guarantees
the best in E-class flexibility:
■■ A wide range of fuel quality
■■ Low emissions even at lower partial
loads
■■ Fast startup
■■ Flexible grid support
■■ Low-maintenance, extended maintenance intervals ­according to customer
needs
■■ Excellent accessibility eases manual
turbine washing and inspection when
firing ash-forming fuel oil

Fuel flexibility –
a broad range to meet different needs
With a fuel range from heavy
fuel oils to low c­ alorific
gases, the SGT-2000E series
delivers high
application flexibility
Siemens has broad experience with
­different types of fuels, including nonstandard fuels like crude oil and low
­calorific gases.
Depending on the fuel composition,
Siemens provides standard combustors
or project-specific solutions.
Thanks to the robust design, the
SGT-2000E series operates at high levels
of reliability – even under challenging
fuel conditions.
Gas turbines in the SGT-2000E series are capable of firing the following fuels:
High performance and low emissions
Standard natural gas
Low-Btu natural gas
Premix burner for standard fuels
SynGas/IGCC/naptha
Fuel oil/heavy fuel oil
Crude oil

Special adapted burner designs for
­unconventional fuels
The SGT5-PAC 2000E and
SGT6-PAC 2000E – Pre-engineered
modules for faster commissioning
The Siemens Gas Turbine
Package (SGT-PAC) ­comprises
the gas turbine and generator,
and all major mechanical,
control, and electrical equipment
­required for safe and reliable
operation of these ­components.
We deliver our Siemens Gas Turbine
Packages largely pre-assembled, including ­piping and wiring to a major extent.
The auxiliary systems are combined in
groups and installed as pre-fabricated
packages. This reduces installation and
commissioning time and expenditures.
Pre-engineered options are available
to meet project- and site-specific
requirements or to increase operating
flexibility and performance of the power
gener­ating system.

Oil and gas business applications:
one engine – many possibilities
In addition to applications
in power plants, the
SGT-2000E series can also
be used for diverse
applications in the oil and
gas industry.
The compressor drive design, derived
from proven standards, can be used, for
example, in the production of liquified
natural gas – either as a direct mechanical drive compressor or as an all-electric
generator version.
